GEORGE A. HILL, or SANFORD, MAINE.

. ADJUSTABLE THRESHOLD-TRANSFER.

Application filed April 28, 1911.

To all whom it may concern Be it known that I, GEORGE A HILL, a citizenof the United States, residing at Sanford, in the county of York andState of Maine, have invented certain new and useful Improvements inAdjustable Threshold- Transfers, of which the following is aspecification.

My invention relates to improvements in devices for marking orindicating the dimensions of thresholds, and has for its object theprovision of a device adapted to measure a wide variety of widths ofdoor openings, consisting in providing an adjustable cross bar withremovable, and replaceable sections, and also in being capable ofregulation to gage the configuration of the door jalnbs so that they maybe ac curately placed in position, the door jamb gages consisting ofarms'adjustably mounted in slots in the ends of the cross pieces,

one of said arms being adapted to engage the face of the jamb, andanother to measure the depth of the door rabbet, when the dc vice is inuse, the rabbet gage having a slot therein and a slotted bar adjustablysecured thereto that is used to measure the length of the rabbet and thedepth of the jamb.

My invention will be described in detail hereinafter and illustrated inthe accompanying drawings, in which:

Figure 1 is a plan view of my improved threshold transfer showing itapplied to a section of a door frame, the cross bar being in twosections, Fig. 2 a similar view show ing the cross bar consisting ofthree sections and the device adapted to measure wide doors, Fig. 3 across section of one ofthe cross bar sections, Fig. 4 is a side view ofthe cross bar in two sections, and Fig. 5 is a side view of the crossbar in three sections.

In the drawings similar reference characters will be used to designatecorresponding parts in the several views.

The cross bar 1 shown in Figs. 1 and 4 consists of two sections; eachsection having a longitudinal slot 3 adjacent to one of its ends and theother end provided with a laterally extending strap 1 rigidly securedthereto by rivets or pins and bent to form hooks 5 opening toward oneanother and spaced from the bar. The edgesof the sections 2 are formedwith notches or recesses Specification of Letters Patent.

6 equi-distant from their hooked ends to receive the hooks 5 inassembling or dismembering the sections 2. In assembling the sectionsthe hooks 5 on their ends are placed in said notches or recesses 6 andthe sections moved to produce the desired width of space or length ofbar and then rigidly secured by the thumb screw 8 shown in Figs. 1 and4. To dismember the bar the thumb screw 8 is loosened and the sectionsshoved lengthwise until the hooks 5 register with the notches orrecesses6 when the sections will readily separate. The end of one or bothsections 2 is provided with a bore 7 to receive a thumb screw 8 to holdthe sections in adjusted positions it being apparent that the sectionsare capable of adjustment in length at any length between the combinedlength of the two sections and the length of a single section.

9, 9 indicates arms each having a threaded bolt 10 secured thereto thatis mounted in one of the slots 3 of the bar 1 and 11 a thumb nut mountedon bolts 10 to hold the arms in position on the bar 1. Arms 9, 9 areprovided with longitudinal slots 11;

12 indicates an arm having a longitudinal slot 13 and 14: a set screwmounted in slots 11 and 13 to hold the arms 9 and 12 in adjustedrelationship. 15 indicates another arm having a screw bolt 16 securedthereto that is also mounted in slot 3 and has a thumb or wing nutthereon to hold it in position on the bar. Arm 15 has one corner cutaway to form a recess 18 to receive the short end of arm 9 when theformation of the door frame is such as to require the moving of the armforward and more or less within the outer straight line of the arm 15.

As shown in Fig. 1 my improved device is capable of adjustment to doorsof different widths and when in use the arms 9 are placed in the rabbetsof the door frame and the arms 12 adjusted thereon so as to measure thelengthof the rabbet and at the same time the width of thedoor j amb. Thearms 15' are then adjusted so that they engage the faces of the jambs.All of the parts of the device being then securely fastened together themeasurements of the door frame indicated thereby may be transferred toany place desired and as many times as found desirable so that all ofthe door frames in a building may be made identical in size with theleast amount of measuring. 7

To provide for transferring the contour of door frames that are widerthan are capable of measurement by the use of a cross bar consistingof'only two sections I propose using a lengthening section 19 havinglaterally extending straps 20 rigidly secured to its ends by rivets orpins-and bent to form hooks 21 opening toward one another and spacedfrom section 19. The middle of the section 19 is provided with. notchesor re- Qcesses 22 in itsedges, the distance from the recesses 22 toeither, end of .the section 19 being equal to the distance from. thenotches or recesses'fi to the hooked ends of sections 2 so that whenassembling the sections 2 with the lengthening section 19 first one andthen the otherof-the sections 2 is slidably engaged with the section'19forming an adjustable'bar of three sections. The straps V and ends ofsection 19 are provided with threaded openings 23 to receive thumb nuts2 1 to hold the sections 2 and lengthening section'19 in adjustedpositions.

25 indicates a threaded opening in the .middle of section 19 to receivethumb screw 26 when the three sections are mounted together. The purposeof :this thumb screw 261s to prevent the sections becoming accidentallydismembered which it does by being screwed down until the end of thethreaded portion extends beneath the section 19 and prevents the hookedend of either of the sec- .tions 2 from registering or getting in alinement with the notches in the center of the section 19;

When the lengthening sectionc19 is to be used in combination withsections 2 the arms :9and 15.0none of the sections 2 are reversed so.thatthe hooks 5 on both sections 2 extend upwardly. The lengtheningsection 19 is then mounted on sections 2, first on one andthen on theother, the thumb screw 26 is then screwed down, and when the bar hasbeen adjusted to the desired width the sections are secured together bythe thumb nuts 24 mounted on the ends of the lengthening section 19.

Having thus described my invention what I claim isc I 1. An adjustablethreshold transfer bar having a longitudinal'slot adjacent each end :andconsisting of sections adjustable one upon the other, a laterallyextending strap oneach of sa1d sections, said straps being on V oppositesides of said sections when assembled and each of said straps bent toform hooks opening toward each otherand spaced from said sections,'andsaid sections being provided with-notches to receive such 9 of' saidhooks asare on the'othersection, means for holding said sections in .anadjustable positiomla pair .of ammsr-ioneof said pair :of

arms being adj ustably secured through one of said end slots in saidbar, and the other 111 the other of said slots, each of said arms havinga recess in its end adjacent said bar, a second pair of armsone of saidsecond pan .of arms being adjustably secured through rigidly securedthereon at each end and notches in its side edges and a thumb screw inits center, said straps beingbentto form hooks opening toward each otherand spaced from said center section, said notches being opposite eachother and equi-distant from said hooks, and said thumb screw being'between said notches, said end sections each having a longitudinal slotat one end and a laterally extending strap rigidly secured thereon atthe other end and notches in their edges, said last named straps beingbent to form hooks opening toward each other and spaced from theirrespective sections and posltioned, to register with the notches in saidcenter, andthe notches 1n said end SBCtlOIlS' so positioned as toregister with said hooks on said center section when said. sections arebeing assembled to form said bar, gage arms mounted on the free ends ofsaid end sections and means for securing said arms in adjustedpositions, said thumb screw in said center section being adapted toprevent accidental separation of sa1d sections.

3. In an adjustable threshold transfer,

an adjustable bar consisting of sections con nected by laterallyextending straps rigidly secured to the ends of said sections and having their ends bent to form hooks, said sections having notches on theiredges spaced to register. with said hooks when said sectlons are belngassembled ordismembered,

and means for securing said sections in an adjusted position, each endof said adjustable bar being provided with a longitudinal slot in whichto secure gage arms.

4. In an adjustable threshold transfer, an adjustable bar consisting ofa center section and two end sections, said center section having alaterally extending strap at each end, said straps being bentlto' formhooks,

thumb nuts in said straps, notches in the center of its edgesequi-distant from said hooks and a thumb screw in its center betweensald notches, said end sections each having a longitudinal slot at oneend and a laterally extending strap at the other end and notches theiredges, said ilfLSfi named straps being bent to form hooks and said lastnamed notches so positioned as to register with said hooks on saidcenter section when said sections are being assembled to form said bar,said thumb nuts in said straps on said center section being adapted tosecure the sections in an adjusted position, and said thumb screwbetween said notches in said center section being adapted to preventaccidental separation of said sections.

In testimony whereof I hereto affix my signature in the presence of twowitnesses.
